1.Comparison of Corneal Injury between Phaco-emulsification and Extracapsular Lens Removal in Rabbits
Journal of Third Military Medical University 1988;0(05):-
40 rabbits are used to study the effects of phaco-emulsification and extracap-sular lens removal or; corneal endothelial cells and corneal thickness.With the specular microscope, the preoperative cell morphology, cell density and thickness of cornea are revealed. The endothelial cell counts decrease 16% (at central) and 14% (at the periphery) after the surgery with phaco-emulsification and 25% (central) and 22% (periphery) with extracapsular lens removal. Corneal thickness increases in both groups. Scanning electron microscopy shows some alterations in morphology of endothelial cell injury significantly different in the 2 groups. According to these results the causes of corneal thickness increasing and mechanism of endothelial cell injury are approached and a new procedure preventing the cell injury and decreasing cornea edema in both groups is designed.
2.Research advances of the effect of commonly used drugs on dendritic cell function and HIV infection
Chinese Journal of Clinical Infectious Diseases 2017;10(1):63-67
Dendritic cells (DCs)can capture HIV from the mucosal site and carry it to the draining lymph nodes to promote CD4 + T cell infection.DC-SIGN(CD209)plays a vital role during this process. Heroin,methamphetamine and cocaine are the most abused drugs used by drug abusers,which can increase the opportunities of HIV infection.Drugs acting on the corresponding receptors activate the downstream signaling pathway and regulate the expression of DC-SIGN on the surface of DCs,weakening the inhibited effects of immune cells on HIV and promoting HIV infection in many aspects.Given the multiplex effects of drugs on immune function,this article reviews the relationship between abused drugs,DCs and HIV infection,particularly in the signal pathway on immune modulation.
3.Clinical study on the treatment of non small cell lung cancer with the combination of Shenqi Fuzheng injection and EP chemotherapy
Chinese Journal of Primary Medicine and Pharmacy 2016;23(17):2580-2583
Objective To observe the therapeutic effect of Shenqi Fuzheng injection combined with EP chemotherapy in the treatment of non small cell lung cancer (NSCLC),and to improve the quality of life and side effects.Methods 60 cases of NSCLC were randomly divided into observation group and control group,30 cases in each group.The two groups were treated with EP,the observation group was treated with Shenqi Fuzheng injection for two courses.The life quality and adverse effects were observed.Results The quality of life of the two groups after treatment was compared,the difference was statistically significant (93.3% vs 70.0%,χ2 =2.83,P <0.05),the quality of life in the observation group was significantly higher than that in the control group.The white blood cell reduction,anemia and liver and kidney function damage between the two groups had statistically significant differences (P =0.011,0.025,0.016),the adverse reaction of the observation group was less than the control group.Conclusion Shenqi Fuzheng injection combined with EP regimen in the treatment of NSCLC can protect bone marrow hematopoietic function and improve the quality of life of patients with NSCLC chemotherapy.It can be used as one mean of Chinese and western treatment for patients with NSCLC in clinical application.

BACKGROUND: The early symptoms of amyotrophic lateral sclerosis (ASL) are usually located at a certain part of the body, and are similar to the clinical manifestations of cervical spondylotic myelopathy (CSM). However, their treatment and prognosis differ greatly. Therefore, multiple-part electromyography and electroneurography possess an important value of reference, particularly electromyography of thoracic paraspinal muscles can be used as an objective parameter for differentiation between ASL and CSM.OBJECTIVE: To investigate the electrophysiological changes in ASL and CSM.DESIGN: A retrospective clinical analysis.SETTING: Neurological Department of Second Hospital Affiliated to Jiangxi Medical College.PARTICIPANTS: Totally 30 inpatients and outpatients with ASL and 30 patients with CSM were selected from the Neurological Department of the Second Hospital Affiliated to Jiangxi Medical College between December 2001 and November 2004.METHODS: Totally 30 inpatients and outpatients with ASL as well as 30 inpatients and outpatients with CSM were subjected to routine electromyographic and electroneurographic examination. Routine electromyography examining three limb muscles + sternocleidomastoid + thoracic paraspinal muscles intended to observe the spontaneous potential at resting stage, time limit and wave-amplitude of motor unit potential, and recruit-ment phase during energetic contraction. Electroneurography was used to detect motsr conduction velocity and sensory conduction velocity,as well as the terminal latency and wave-amplitude of motor evoked potential.limb muscles, sternocleidomastoid and thoracic paraspinal muscles in paASL and SCM.RESULTS: Data of all the 60 patients entered the final statistical analysis.in patients with ALS and CSM, and were more severe in the former. The abnormality rate of spontaneous potential of thoracic paraspinal muscles reached 93.3% (28/30) as compared to 3.3% (1/30) in patients with CSM (P < 0.001). The average time limit and abnormal increment of wave amplitude of motor unit potential were significantly different in patients with conduction velocity: The decrease rate of motor evoked potential amplitude of complex muscles was obviously higher in ASL than in CSM (75.6% and 86.7%, ~=7.25, P < 0.01). So was the decrease rate of motor conduction sory nerve conduction velocity: It was not affected either in ASL or CSM.ALS and CSM, but the abnormality rate of spontaneous potential of thorography indicates that nerve conduction velocity was not affected in both playing decreased conduction velocity and wave amplitude than those with CSM.

Objective To evaluate quantification of metamorphopsia in eyes with idiopathic macular hole (IMH) before and after surgical treatment, and investigate its relationship between postoperative visual acuity, the macular hole index (MHI), and the macular hole prognostic factor (HPF). Methods Thirty eyes of 30 patients, who underwent successful vitrectomy and internal limiting membrane (ILM) peeling for IMH and were followed up more than 6 months, were included in the study. The uncorrected visual acuity of the fellow eyes was better than 20/25 and there was no metamorphopsia in that eye. The macular hole closure was confirmed by optical coherence tomography (OCT) scans. Metamorphopsia was evaluated by metamorphopsia-charts (M-chart). OCT, best corrected visual acuity (BCVA) and metamorphopsia were obtained before and after surgery. Vertical (MV) and horizontal (MH) metamorphopsia, macular hole index (MHI, the ratio of the height to the diameter of the base) , and macular hole prognostic factor (HPF,the ratio of the height to the minimum diameter) were measured. The metamorphopsia score was the average value of MV and MH. SPSS 16. 0 statistical analysis software was used for data analysis. Results Preoperative MV and MH were (1.82±0.04)° and (1.81±0.04)°, respectively. Six months after surgery,the MV and MH were (0.17±0.03)° and (0.11±0.03)° respectively. There was significant difference between pre- and post-operative metamorphopsia results (Z=-0.788, P<0.05). The metamorphopsia score at 6 months after surgery were positively correlated with the value of the postoperative BCVA (LogMAR) (r=0.540, P=0.004) and negatively correlated with the values of preoperative MHI and HPF (r=-0.676,-0.518; P<0.05). Conclusions Successful vitrectomy and ILM peeling can improve metamorphopsia of IMH. Postoperative metamorphopsia was correlated with the postoperative BCVA and the preoperative macular hole contour.

Oncolytic viruses,a novel class of virus vectors,which selectively replicate only in tumor cells,have excellent tumor targeting and good tansfection efficiency.Many oncolytic viruses have apparent curative effect when administered intratumorally.However,the host immune system remains a critical obstacle to systemic administration of virotherapeutics.It appears that cell-based delivery of oncolytic viruses could offer one solution to this critical problem,which provides a new platform to the biological therapy of cancer.
